How fast can this gearbox spin?

[@galinrashkov7645]

I would recommend using bearings on each wheel and decrease significantly the gaps between the different gears (Use teflon rings)

[@zeicanofficial]

Exactly what I was thinking, I was really thinking it would significantly decrease friction.

[@ghostlyninja125]

Journal bearings would be best

[@Xavier1...]

I'm guessing that adding a lubricant like oil would also decrease friction? Maybe transmission fluid idk?

[@wachocs16]

Also add a chanfer on the bed side of the print. You can se the first gold gear to have a big elephant foot (Layers squished at the bottom) and maybe add grease Teflon or brass washers would be good to pack them more thingly and reduce vibration Also this type of gears are really dangerous at high speed. Never be over the axis of rotation. If you reach really high speed inside your house you can get your ceiling damaged, electrodomestics and pets

[@oeliku3033]

Some suggestions: 1. use spacers on the axle, so the gears are fixed on there to prevent wobbling and gears grinding against each other 2. use a normal M8 steel bolt instead of the aluminum rod and screw it far enough in, so you dont get vibrations in the gears. That way, the gears wont come loose as well 3. use ball bearings on the housing AND the gears 4. reduce the contact area of the higher gears. So 1st gear has the most contact area and so on 5. lube the gears and bearings 6. print the grip sideways. so it doeant brake (obvsly) 7 maybe try different gear geometries. there a some that are better for high torque or high speed. the latter have much less drag. 8. you can safe an enourmous amount of weight on the last gears. make them much thinner then they are now

I've had a curiosity for a long time: how to extract energy from something that's very heavy, but moving very slowly. I present the challenge to you: how much energy can you extract from a falling weight? Or, how long can you keep a system moving, while only dropping a weight a short distance? Ultimately, the scenario that fascinates me most is glaciers. It would seem there's a very large amount of potential energy there.

[@SjaakWWortel]

While you are there, wait for the tundra to melt, now you increased the arable land 4000% near the artic.

You also get more wind power as a side effect, perhaps even too much of it, as more energy is freed into the system, a couple of tornadoes here and there, not big of a deal. And your coastal lines might change by a couple of meters. That's a minor deal thou, who would build anything on beaches anyway. Lots of erosion already.

In the early 1980's a New Zealander was watching a coin spinning on its edge but face down until it eventually fell flat and stopped.

Are you familiar with it? because as like "Epilogics" infinitely variable transmission that supposedly could handle large torque loadings both seem to have disappeared.

Great video. One tip, get some cutting oil and use it when drilling metal. You'll spin the drill slower but it will cut faster and cooler. When it's cooler it'll wear your bits less and cut the metal smoother. If you get it and don't agree I will pay you the $10 for the oil. No joke.

Why not try helical or herringbone gears, they would have a more consistent transfer of power. Also what did you use to lubricate them? With the high speeds of the last few gears the lubricant may just get flung off.

[@judeackland-patel6646]

The main reason you can't get it any faster is friction between the gears and the shafts. This is exacerbated by oscillations caused by the very low tolerances you're maintaining to keep everything moving. The frictional torque especially in the faster moving gears is amplified by the gear ratio, which makes it very hard to rotate the slower moving gears at a decent speed. If you use cheap steal bearings, you won't have nearly as much friction and you you'll be able to keep tolerances high, leading to less parasitic oscillations. Keep making :)

[@devinwalton408]

Fuck it, needle rollers.

[@EnjoyCocaColaLight]

So. Enough gear ratio that a dropped weight of a few tonnes, pulling a chain, will cause a serious amount of power generated (think power plant), and when at the bottom - disconnect gears while pulling the weight back up, re-clutch the gears, and let gravity power the power plant once more. Do this with enough gears and you literally have perpetual motion.

[@exitusthirteen]

No, because he is putting in high torque at low speed and the last wheel could only put out low torque at high speed. So the amount of energy would be the same (minus friction). This construction is only a gearbox. Typically it is used to transfer the mechanical energy from an turbine to a generator, which will convert the mechanical energy to electricity.
